Specification of Letters Patent.

Patented July it), 1917.

Application filed August 23, 1916. Serial No. 117,217.

To all whom it may concern:

Be it known that T, ALVAN B. BROWN, a citizen of the United States, residing at Grand Rapids, county of Kent, State of have invented certain new and useful Improvements in Sprayers, of which the following is a specification.

This invention relates to improvements in sprayers.

The objects of this invention are to'provide an improved sprayer the structure of which is simple and durable, which is adapted to produce sprays of difierent character and which is very easily manipulated to pro- '15 duce such results and which constitutes a valve.

A further object is to provide an improved sprayer which is not likely to clog and should it become clogged is readily freed from the obstruction.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

T accomplish the objects of my invention by the devices and, means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated so in the accompanying drawing, forming a part of this specification, in which:

Figure I is a side view of a sprayer device embodying the features of my invention.

lFig. H is a central section through the nozzle of my improved sprayer, parts being shown in full lines.

lFig. HT is a plan view of the plunger.

Fig. TV is a side view of the plunger.

Fig. V is a slightly modified structure embodyin the] features of my invention.

Fig. l is a plan view of the plunger of the modified structure shown in Fig. V.

Fig. W1 is a section on a line correspond- 45 ingto line 7-7, of Fig. VT.

ig. VIII is a central section of another modification of my invention.

Tnthe drawing similar reference characters refer to similar parts throughout the to several views, and the sectional views are taken looking in the direction of the little arrows at the ends oithe section lines.

Referring to the drawing, the nozzle body 1 is provided with a nozzle chamber 2 termiv mating in a plunger cylinder portion 3 at projection its outer end. At its inner end the nozzle chamber has an internally threaded inlet connection 4 for the delivery pipe 5. The delivery pipe 5 is provided with a handle or grip portion 6, the hose 7' being connected to the butt of this grip portion.

The body 1 of the nozzle is externally threaded at its outer end. to receive the tip member 8. The tip in the structure illustrated is formed of the member 8 and a disk-like member 9 having the discharge orifice 10 therein, the member 9 being retained within the member 8 by the annular flange 11 thereof. I

An annular gasket 12 is disposed between the disk 9 and the end of the body 1, the disk member 9 being clamped thereon by the tip member 8. The plunger 13 is arranged to reciprocate in the cylinder portion 3 and is provided with a stem 14: proecting through the opening 15 in the inner end of the body member at the side of the pipe 5.;

A packing gland 16 is provided for the plunger stem. The plunger is adapted to set against the gasket 12 and constitutes a valve for the nozzle. The plungeris provided with diagonally disposed peripheral groove-like passages or ports 17 which are closed when the plunger is seated. The inner end of the plunger is beveled at 18 so that when the plunger is retracted this beveled portion passing from the inner end of i the cylinder portion provides supplemental portage, such supplemental portage is not, however, brought into action until the plunger has been moved a considerable distance.

The pressure of the spraying fluid tends to seat the plunger and will normally accomplish that result. I, however, prefer to employ'a spring 19 which is arranged on the stem of the plunger to normally hold the plunger in its initial or closed position. This spring is of considerable advantage in that it provides a resistance or the operator to pull against in manipulating the plunger actuating lever 20. The lever 20 is pivoted at 21 on the clip 22 carried by the pipe 5, the lever being connected by the link 23 to the plunger stem.

The plunger is provided with a needle-like 24: which projects into the delivery orifice 10 when the plunger is seated so that it is effectively freed from any obstruction which may collect therein,

In the modification shown in Fig. V the spring 1 9 is omitted. The ports 1'4" in this I modification are formed in the body of the broad short spray is secured. As the plunger is opened farther the spray is lengthened and narrowed. When the plunger isopened to bring the beveled portion thereof into action to secure the additional or supplemental portage a forceful spray is delivered.

When the plunger is fully opened a long narrow forceful spray is deliy'ered, so that by simple manipulaticns I am able to produce a large range of sprays, that is, sprays of different character in order to meet the various requirements in practice and this simply by manipulation of the plunger 1ever. When the plunger lever is released the pressure will close it. When, closed the plunger constitutes a valve, cutting off the spray and preve'ntingany loss of the spray solution. A further advantage of cutting ofi at the nozzle is that it preventsthe dripping of the spray solution on the handle and also the loss of the spray solution which would be contained within the rod and the tip, it being common practice to arrange the valve at the handle. A further advantage of the construction is that by being able to fully control the spray it may be regulated to meet the requirements for spraying a small tree or shrub, a large tree or the trunk or limbs of a tree, thus enabling the placing of the spray solution in a very effective manner and as desired.

sob

p I have illustrated embodiments which I have found to be very satisfactory. I have not attempted to illustrate or describe other embodiments of my invention as I believe the disclosure made will enable those skilled in the art to which my invention relates; to
